The latest must-have for anyone with a television and stereo system these days is a home theater system. As usual we have to have for-the-better society, most people think big, that if the ideal home theater of their dreams. How big? You know, big screen, big sound from a powerful receiver and amplifier, and the big sound from speakers distributed throughout the room.
But once the dream dissolves into the real world many of us to realize that this configuration does not work great in our homes. Wenot space for all speakers. Finally, five speakers and a subwoofer take a considerable amount of space. Or maybe we just do not want wires around the base boards. Or do not want the hassle of creating technical and balance this large system.
Fortunately, those with limited space, or even ideas of minimalist design options. The allure of surround sound can be approached in different ways. The technology has gradually developed and whatcalled virtual surround. Virtual surround sound is designed to imitate the sound characteristics of a multi-speaker. Although it uses fewer speakers and wires, a virtual system approaches the overall sound of an amplifier and 5.1 or 7.1 speaker system. There are two main types of virtual systems, 2.1 surround sound system and digital projection system.
The default positioning for a 2.1 speaker system is in place with two speakersPublic, together with a sub-woofer in the room somewhere inconspicuous. The new system is the effect of a larger install 5.1 which has 5 speakers and subwoofer. On the other hand, digital sound projectors come with a single strip of relatively small speakers that produce sound. In most cases, the digital audio system has a sub-woofer.
In any case, even if the setting is different, there's the same basic principle. The technology behind the system is based on aKnowledge of how people sound internal process There are some techniques used to change the sound waves to the human ear into thinking that there are more speakers of what is really there to deceive. These techniques of psycho-acoustic studies, or study the way people perceive, are healthy. To fully appreciate what he has done the technique, you must understand at least some 'of psycho-acoustics, acoustics and physics (the science of sound).
